[Milsurplus] what is this old power supply?

[WA5CAB at cs.com]

One of two HV power supplies out of the BC-640-(*) VHF AM transmitter.  220 
VAC transformer primaries (no 110 tap).  1000/500 VDC output.  And some 
filament supplies but I'd have to look at the T.O. to get the details.  The 5Z3 
rectifiers (which are full wave) are connected as half wave (both plates tied 
together) and the four are connected in a bridge rectifier circuit.  Hence the dual 
output.
